Specific embodiment
The utility model is further described with specific embodiment below with reference to accompanying drawings:
Fig. 1 is the structural schematic diagram of the vehicle frame fore device with crusherbull zone function of the present embodiment.Before the vehicle frame
End device includes frame front cross beam 1, longitudinal beam 2, extension bracket 3, flat spring bracket 4, lower protection crossbeam 5 and flat spring bracket crossbeam
6, one end of the extension bracket 3 and one end of flat spring bracket 4 connect firmly integrally, then connect with longitudinal beam 2；The vehicle frame
Front beam 1 is connect with the other end of extension bracket 3, and the lower protection crossbeam 5 is connect with the other end of flat spring bracket 4, the plate
Spring bracket crossbeam 6 is installed on 4 side of flat spring bracket.
From figures 2 and 3, it will be seen that the frame front cross beam 1 includes front beam leading portion 11 and front beam back segment 12, preceding cross
Beam leading portion 11 is arc-shaped, and front beam back segment 12 is frame shape.Front beam leading portion 11 and front beam back segment 12 are enclosed cushion space
13.Front beam leading portion 11 is equipped with 6 through-holes 111, and the shape of through-hole 111 includes ellipse and triangle.The front beam leading portion
11 are equipped with horizontally disposed energy-absorbing muscle 112, and the energy-absorbing muscle 112 is groove.
In Fig. 4, the middle part of the flat spring bracket 4 is inlaid with bushing 41, the lining close to 2 lower aerofoil position of longitudinal beam
Set 41 and the clearance fit between longitudinal beam 2 and flat spring bracket 4.The top of the flat spring bracket 4 is equipped with defining flange 42, institute
State defining flange 42 and clearance fit.
Fig. 5 is the sectional view of lower protection crossbeam.The lower protection crossbeam 5 is hollow structure, is internally provided with several and adds
The cross section of strengthening tendons 51, the lower protection crossbeam 5 is L-shaped.
When vehicle collision position is higher, front beam leading portion 11 deforms up to crumple, due to front beam leading portion 11
Deformation and crumple absorb part Impact energy, reduce the impact energy for being transmitted to personnel and vehicle, cargo, simultaneously because slow
The presence for rushing space extends buffer time, and due to front beam back segment 12, longitudinal beam 2, extension bracket 3 and leaf spring branch
The tensile strength of frame 4 is greater than front beam leading portion 11, so as to preferably keep the complete of vehicle frame front-end architecture, and then protects attached
